US Patent 12109836 Ballpoint dot pen tattoo cartridge

A ballpoint dot pen tattoo cartridge includes a ballpoint pen element comprising an ink reservoir housed within a tapered bottom barrel providing a first barrel aperture and flanged top surface. A second barrel aperture in cylindrical top of the barrel includes a diameter larger than the first aperture with an assembly to attach the barrel cylindrical top to a tattoo machine. A resilient element within the barrel is sized to receive the ballpoint pen element between the first barrel aperture flanged top surface and two equal sized tabs on the ballpoint pen providing exit and retraction of the ballpoint pen assembly for ink discharge from the cartridge barrel tapered bottom whereby a tattoo machine operator controls the driving actuation of the tattoo machine to the ballpoint pen tip for controlling inked markings of a material.
